"Tools>Options>Visual Micro>Compiler>Project Folder -I" is now enabled by default. This allows local files to be #included using <foo.h>. Previously only #include "foo.h" was supported unless the above tools>option was enabled. The option as the project folder as a -I compiler include.

Fix: It was possible to cause a linker error (.o object already defined here xyz...) with local library sources especially with a conflicting shared library project of the same name but different location causing duplicate .o files to be linked. This could easily have caused much confusion!
